As I recall, the original intent of the new rules was to let people align the cube. The WCA did not expect that people would base their entire solving technique around using the table to hold pieces in place, and indeed, I don't remember anyone seriously practicing that technique before the rule change. However, although I'm not one of those people who regularly aligns layers using the table, I don't really see a problem with other people doing it occasionally. Specifically, I wouldn't want to DNF them for it.
Wrong. One of the biggest difficulties of OH, especially big cube OH, is using the same hand to hold the puzzle and make turns. If you constantly use the table, you are essentially removing one of those requirements - you no longer have to use that hand to hold the cube. So one table's just doing turns, and then the only difference between that and a non-ambidextrous 2h solver is that the 2h solver can move parts of the cube-holding device out of the way of the turning layers.
You might as well say that someone in power can't abuse their authority because they are already allowed to use that authority.
It didn't used to be that way, back when a lot of OH big cube limits were being broken. Having to specify that OH cube solves are done in the air is a recent development and one which I oppose.
And dropping does happen, unfortunately.
Irrelevant. The point is that you can abuse something that you are allowed to use.
